I installed these on my GTS, and just be forewarned that there is some cutting involved for the mounting bracket. If you have a spouse, make sure you tell them what you're doing beforehand so they don't walk out and see you taking a saw to your Viper. I won't repeat what my wife said, be she was VERY curious as to what I was doing. The kit comes with a template so you can mark exactly where the line is, and I probably double, triple and quadruple checked my measurements prior to cutting. The new system is so far superior to the factory system that you'll kick yourself for not doing it sooner. When I show people the little piece of crap that WAS the back brake they just shake their head. Now it's used as the parking brake, and that's about all it's good for. When you consider what a new hood costs, this is actually a pretty good bargain. I had mine on in a day, and did them in my driveway with common tools. It is by far the best, most practicle mod I've done on my car.
